a.It should be afford of such a test: Applying AC1500V between terminal and out

can for 1min, there should be no damage, or creeping action;

b. Applying AC660V between two contacts for 1min, there should be no damage,

or creeping action

Approval: UL, VDE, TUV, CQC, RoHs compliant

Endurance Test:

Low temperature endurance test:

1.Place the product in a constant temperature cabinet with temperature of

-20±3°C for 1 hour after the temperature becomes stable.

2. Take it out, then carry out high temperature endurance test according to clause 3.8. after 2 hours being placed in normal temperature environment.

High temperature endurance test:

1.Place the product in a constant temperature oven with temperature setting 150±3°C for 1 hour after the temperature becomes stable.

2. Take it out, then carry out low & high temperature shocking test according to clause 3.9. after 2 hours being placed in normal temperature environment.

Temperature shocking test:

Put the product in a constant temperature cabinet with -20±3°C for 0.5h,

then take it out in normal temperature environment for 2~3min,and then

put it in a constant temperature oven with 150±3°C for 0.5hour, thereafter

again take it out in normal temperature environment for 2~3min. After above 5 cycles tests, the temperature shift should be within ±3%°C of original temperature.

Humidity endurance:

After being placed in a constant temperature cabinet with 40±3°C, relative humidity 90%~95% for 48 hours, the insulation resistance between terminal and out can should>10MΩ;

Dropping test:

From 200mm high, freely drop the product to cement ground and other hard flat material with its six different sides (face, reverse, left, right, front, back), one time dropping for each side. The temperature shifts should be within ±3%°C of its original action temperature.;

Time endurance test:

The temperature shifts should be within±3%°C of its original action temperature after 1000,000 cycles performance under rated voltage and rated current condition.
